摘要

Impact of Larimichthys crocea cage culture in Daiqu fishery(Zhoushan,Zhejiang Province)on the chemistry of the sediment was investigated.Sediment samples,in different depths and from three stations at various distances from the cage,were collected,for analyzing total organic matter,total organic carbon,total nitrogen and phosphorus.The results showed a significant increase in all analyzed parameters in station 1,at 5m from the cage.The difference between reference station(600 m from the cage)and station 2 at 95 m to the cage was insignificant,indicating localized impact of cage farming to the vicinity of cage.The analyzed parameters in various depths did not show a significant difference.The values of analyzed parameters in the perimeter of the cage and their differences with reference stations showed small magnitude and localized impact on the chemistry of sediment.It might be because of deep water and moderate velocity of water current in this fjord.The magnitude of impact may differ during the summer when biomass and feeding rate would be at the maximum level.
